摘要

带正电的吖啶(和相关)染料在正烷基硫酸钠形成的阴离子胶束中的吸收(增溶)速率染料进入胶束的机制是一个两步过程,涉及染料的快速(扩散控制)吸附。在表面活性剂的临界胶束浓度(CMC)以下,观察到染料和表面活性剂的时间依赖性结合,从而产生较大的agg

Dynamics of small molecule-micelle interactions. A stopped-flow investigation of the kinetics of absorption of acridine (and related) dyes into anionic

The rates of absorption (solubilization) of positively charged acridine (and related) dyes into anionic micelles formed by sodium n-alkyl sulphates

The mechanism proposed for incorporation of dye into the micelle is a two-step process involving a very rapid (diffusion-controlled) adsorption of dye

Below the critical micelle concentration (CMC) of the surfactant, a time-dependent association of dye and surfactant is observed, which gives large agg
